COMBINED SPIDER ANB GAS. SA.

l Application led September 19, 1923. Serial No. 4663,641.

To all whom t may concern:

Be it known that T, HARVEY R. STANDLEE, a citizen of the United States,residing at Tulsa, in the county of Tulsa and State of UklahOma, haveinvented certain new and i useful llmprovements in Combined Spiders andGras Savers, of which the following is a specification, reference beinghad to the accompanying drawings.

This invention relates to a combined spider and gas saver and hasrelation more particularly to a device of this general characterespecially designed and adapted for use in connection with the laying orwithdrawing of tubing in an oil or other deep wells and it is an objectof the invention to provide a novel and improved device of this generalcharacter which, when in applied position, serves to prevent the passageof oil or gas up through the casing and out through the spider.

Tt is also an object of the invention to provide a novel and improveddevice of this general character provided in one end portion with asocket to receive requisite slips whereby it is possible to lay orwithdraw the tubing with a sin e elevator yet which can also be employedwith equal facility with two elevators.

Another object of the invention is to provide a novel and improveddevice of this general character comprising a tubular meinber havingthel intermediate portion of its bore enlarged to receive suitablepacking to engage a tubing disposed therethrough to prevent leakage ofeither oil or gas and which packing is yieldably supported in order tofacilitate the passage through the device of the collars comprised inthe tube line and also to assure the packing having requisite engagementwith the tubing.

An additional object of the invention is to provide a novel and improveddevice of this general character provided with interior packing forengagement with an inserted tubing together with means for adjusting thepacking to maintain the same in proper contact with the tubing.

The invention consists in the details of construction and in thecombination and arrangementv of the several parts of my im-.

ient andA advantageous for use, as will be hereinafter more fully setforth.

The novel features of my invention will hereinafter be definitelyclaimed.

Tn order that my invention may be the better understood, T willnowproceed to describe the same with reference to the accompanyingdrawings, whereinz- Figure 1 is a view partly in section and partly inelevation illustrating a combined spider and gas saver constructed inaccord-A ance with an embodiment of my invention 4 and in appliedposition;

Figure 2 is a sectional view taken substantially on the line 2-2 ofFigure l;

Figure 3 is an elevational view of the inner or straight face of -one ofthe sections of the spider as herein disclosed; and

Figure 4 is a view in perspective of a pair ofslips as herein disclosed.

As disclosed in .the accompanying drawings, my improved spider Scomprises two duplicate sections l which, when assembled, provide asubstantially cylindrical member of requisite dimensions and theopposite end portions of each of the sections 1 have disposed around theouter periphery thereof the recesses or channels 2, the outer wallsla ofwhich being beveled or inclined.

As particularly illustrated in Figure 1 the spider S is mounted upon thecasing head H and rests upon a packing ring 3 carried by the upper endportion of the casing head H and threaded through the adjacent Wall ofthe head H are the holding screws 4, the inserted end portions of whichhaving direct contact with the beveled or inclined walls of the channelsor recesses 2 and in a manner whereby the assembled spider iseffectively maintained in working position.

The intermediate and preferably the central portion of the bore of theassembled spider 1s enlarged, said enlargement being defined byregistering pockets or recesses 5 provided in the opposed faces of theassembled sections 1, each of said pocketsl being substantially U-shapedin cross section. Substantially snugly fitting wlthln each of thepockets or recesses 5 is a follower plate 6 also substantially U-shapedin cross seetion and having its open face disposed toward the boreproper of the spider S. The plate or cup 6, however, is of a depth lessthan the depth of the associated recess or pocket 5 so that said plateor cup 6 is capable of movement therein. f

Snugly fitting within each of the plates or cups 6.is a packing 7 ofrubber or other suitable material and the inner face of said packing 7is provided therealong with a groove or channel 8 adapted to snugly.receive the adjacent portion of a tubing T disposed through theassembled spider and fin a manner whereby said packing serves toeectually seal the bore of 'the assembled spider against the flow of oilor gas other than through the tubing T.

Each of the sections 1 at substantiallythe centralportion of the pocketor recess 5 is provided with an opening 9' in which is adapted to bethreadeda speed screw 10 o1' the like. Interposed between the insertedend of the screw 10 and .the intermediate porvtion, of the plate.or cup6 is an expansion member 11, herein disclosed as -a coil spring,

said member or spring in addition to con-v stantly urge the cup or plate6 inwardly of the spider also provides yieldable means whereby a collar12 comprised in the tubin T may readily pass through'thespider and moreparticularly `between thev opposed packings 7. y

By having each of the plates or cups 6 substantially U-shaped in formthe packing 7 applied therein is effectively maintained .'a'gainstmovement in a direction circumferentially of the tubing with which thesame engages and which movement is further.

prevented by the cross sectional conguration ofthe pocket or recess 5in`which said cup or plate is arranged.

One end portion of the'bore of the assembled spider S is enlarged, as at14, to provide a socket with the lside walls thereof tapered inwardly,as illustrated in Figure 1. In laying or withdrawing of pipe with asingle elevator, as is well known in the oil fields or in connectionwith othe'rdeep wells,

fthe slips 15 are inserted withinthe enlarged portion or socket 14 andthe tapered wall of thev socket' 14 coacts with the outer or con-..vex'facesl of said slips to cause the teeth 16 provided on the inner or-concave faces of Esaid' slips to have requisite engagement with thetubing T to hold the same 4during the period the position ofthe'elevator is bemg changed. It is to be understood that during thedifferent operations of the elevator, ,the slips 15 are removed andapplied.

v.As herein disclosed, the slips `15 are assembled in pairs and arepivotally en'gaged with the parallel arms v17 of a yoke member, theouter end portions of said yokemember being laterally extended, las at18, to provide means whereby the slips maybe readily and convenientlymanipulated.

l vWhen my improved spider is'adapted for`I use in connection with thelaying or withdrawing of pipe .with a plurality of elevators it 1spreferred that the end portion of" the assembled spider -provided withva socket 14be directly engaged with the casing head as the bore of theassembledspider at such end is of a diameter to permit such operation.

While the expansible members or springs 11 serve to constantly urgelthepacking 7 into proper en gement witha tubing T it is also to beungeirstood that the speed screws 10, when a-tubing is first insertedthrough the spider, are properly adjusted to assure the requisitecontact of the packing 7 ,with

the portion ofthe tubinginterposed between suchpackin y The sections; 1of the spider S may be held in assembled vrelation in an `desired mannerbut as herein disclosed lemploy the bolts 19 and coacting nuts 20 as isclearly illustrated in- Figure 2 of the. accompanying'dra'wings.

rom Ithe foregoing description it is thought to be .obvious that acombined spider and gas saver` constructed in accordance with myinvention is particularly well adapted for use by reason of theconvenience and facility with which it may beassembled and operated,andv it will also be obvious thatv my invention isy susceptible of somechange and modification without departing from the principles and spiritthereof and for this reason I do not wish'to be understood as limitingmyself to the precise arrangement and formation of the several partsherein shown in carrying out my invention'in practice except ashereinafter claimed.

I claim .v A combined spider and gas saver comprising a tubular memberadapted to be` mounted upon a casing head, an intermediate portion lofthe boreof the spider being enlarged to provide opposed pockets eachanular inl cross section, a substantially -shaped plate snugly en'gagedwithin each of said pockets, a packing snugly engaged Within each ofsaid plates, the opposed faces of the packing being grooved to properlyengage a tubing inserted throu h the spider, each of the pockets beingof a epth greater than the depth ofthe plate, said plate being movablewithin the` pocket, said spider having openings in the wall thereof,each of said pockets 'having an o ning in communif cation therewith, a,mem r threaded within each of -said openings, and an expansible memberinterposed between the inserted end of each ofsaid first named membersand-the v adjacent late. l

In testimony whereof I hereunto ,ailix my signature.

HARVEY `I,c.'sriiiuzirnn.
